+Finds copy constructors where the constructor don't call 
+the constructor of the base class.
+
+.. code-block:: c++
+
+    class Copyable {
+    public:
+      Copyable() = default;
+      Copyable(const Copyable &) = default;
+    };
+    class X2 : public Copyable {

+    };
+
+Also finds copy constructors where the constructor of 
+the base class don't have parameter. 
+
+.. code-block:: c++
+
+    class X4 : public Copyable {
+      X4(const X4 &other) : Copyable() {} // other is missing
+    };
+
+The check suggests a fix-it in every scenario including multiple 
+missing initializers and constructors with template argument.
